My story is pretty simple. I am a chronic PTSD sufferer and have found that maintaining my aquarium helps keep my mind off the bad stuff and focused in positive way. I've had aquariums before but I've never poured as much into them as I have into the one of have now. I spend most of my time in my garage (isolation, part of the condition), so I set it up in there and I find myself eyeballing it constantly. A day doesn't go by that I'm not working on it in some form or fashion. I even built the stand.

Anyway, I spend most of my time at work staring at a computer screen and thought it would make sense to carry this obsession over and think about aquariums 15 hours a day.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian.[unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
